PALLADIUM CATALYST SYSTEM COMPRISING ZWITTERION AND/OR ACID-FUNCTIONALIZED IONIC LIQUID

摘要

THE PRESENT INVENTION CONCERNS A CATALYST SYSTEM IN PARTICULAR A CATALYST SYSTEM COMPRISING PALLADIUM (PD), A ZWITTERION ANTI/OR AN ACID-FUNCTIONALIZED IONIC LIQUID, AND ONE OR MORE PHOSPHINE LIGANDS, WHEREIN THE PD CATALYST CAN BE PROVIDED BY A COMPLEX PRECURSOR. SUCH AS PD(CH3COO)2, PDCI2, PD(C H3COCHCOCH3), PD (CF3COO)2, PD(PPH3)4 OR PD2(DIBENZYLIDENEACETONE)3. SUCH CATALYST SYSTEMS CAN BE USED FOR E.G. ALKOXYCARBONYLATION REACTIONS, CARBOXYLATION REACTIONS, AND/OR IN A CO-POLYMERIZATION REACTION, E.G. IN THE PRODUCTION OF METHYL PROPIONATE AND/OR PROPANOIC ACID, OPTIONALLY IN PROCESSES FORMING METHYL METHACRYLATE AND/OR METHUCRYLIC ACID. CATALYST SYSTEMS ACCORDING TO THE INVENTION ARE SUITABLE FOR REACTIONS FORMING SEPARABLE PRODUCT AND CATALYST PHASES AND SUPPORTED IONIC LIQUID PHASE SILP APPLICATIONS.
